Speaking of, Richard finds Bailey and tries to engage her in conversation. He tells her it's not like her to not want to talk, so she marvelously turns the tables on him and asks about his wife. This helps us, the viewing audience, to learn that Adele isn't taking Richard's calls and hasn't let him move back home yet. Realizing he got distracted, he yells at her to talk. But when she asks if he's ordering her to talk, he says no, so she says goodbye.
Cristina tells Derek that Henry's family is on their way, and he uses the moment to ask her for a drink. Not like that, people! He's got enough subordinate dating issues already; this is a totally innocent question. She's suspicious, and doesn't want to go because she doesn't like him. He asks, "You don't like me because of Meredith?" Cristina: "I don't like you because you're you." He ponders this, seeming to accept it with no problem, and asks how Meredith is. Naturally, she's "fine," which he says is her problem. Cristina smoothly states, "We're fine people, we do fine! We're fine." She then asks how Burke is and if he's off that day, not as nonchalantly as she thinks. Derek for once goes the direct route and tells her gently, "Dr. Burke handed in his letter of resignation two weeks ago. He wanted me to tell you." This clearly shakes her up, but when he apologizes, she tells him not to, since she's "fine." He walks away, and she tries to do paperwork, but is fighting a losing battle to give off an air of "fine."
